From the breakdown of topological quantum memory to mixed-state topological order
内容： Topological quantum memory can protect information against local errors up to finite error thresholds. Such thresholds are usually determined via the decoding algorithms rather than the intrins...

Algorithms for simulating thermal quantum many-body systems: quantum computation, tensor networks and neural networks
内容： Simulation of quantum many-body systems is extremely challenging, as computational resources (time, memory) grow exponentially with system size. In this talk, I will introduce one classical and...

Renormalization-group Perspective on Gravitational Critical Collapse
内容： In this talk, we discuss how to interpret the critical gravitational collapse processes via renormalization group (RG). As an instructive example, we propose extremal black holes (BH) as critic...
